How F1 can do more to balance driver weight

This is something I have been advocating for years because it just isn't correct for someone who would healthily weigh 75kg to go on a diet just because the car is overweight.

In the 1980s and '90s, the weight of the driver was not part of the overall car weight and there were minimum cockpit length dimensions, so small and light drivers were the order of the day.

While that all changed, and for the better, there is still more that needs to be done.

If the planned changes are brought in for 2019 then I hope the rules take into account all the factors related to the driver fitment and weight.

The cockpit length is still a little too short for drivers of the size of Nico Hulkenberg, and because normally the taller you are the heavier you are a small increase of, say, 5cm, would make a big difference to how a tall driver sits in the car.

If they are going to use a driver weight of 80kg, then if you have a 65kg driver you will need 15kg of ballast.

If that can be mounted low down (below the seat) then there is still an advantage for the small, light driver as this will lower the centre of gravity.

This ballast needs to be mounted on the seat back bulkhead and spread out over a certain area that is relative to the centre of gravity of the driver. That way, smaller and lighter drivers will not get any advantage.

If the minimum cockpit dimensions for seat back to front bulkhead were increased by this 5cm, this could be checked before fitting any driver ballast.

The fact that lighter drivers are normally shorter means the seat back to seat bulkhead gap will increase, meaning there will be room for the extra ballast.
